Effects of Intranasal Fluticasone Plus Azelastine on Airway Inflammation in Patients With Asthma & Allergic Rhinitis (MAN06)

April 4, 2019 updated by: University of Dundee

Proof of Concept Study to Assess Downstream Effects of Using Combined Intranasal Fluticasone Propionate Plus Azelastine Nasal Spray on Asthmatic Inflammation in Patients With Persistent Asthma and Allergic Rhinitis

Single centre, double-blind, placebo controlled, adaptive design, cross-over trial. The primary objective is to assess the additive effects of using combined intranasal fluticasone propionate plus azelastine nasal spray on airway hyperresponsiveness. This is in patients with persistent asthma and allergic rhinitis, receiving inhaled steroid.

Study Overview

Detailed Description

The unified allergic airway describes patients who have both asthma and allergic rhinitis. Both conditions have similar underlying pathophysiology in terms of T-helper 2 (Th2) cell activation. Patients with unified allergic airway disease have a greater burden in terms of impaired quality of life, and the presence of airway hyper-responsiveness (AHR) to methacholine is a hallmark of their underlying asthmatic inflammatory process. Targeting the Th2 allergic airway with a topical antihistamine may improve airway hyperresponsiveness.

It has previously been shown that in patients with unified allergic airway disease, using inhaled fluticasone alone (100 micrograms per day) produced a 1.2 doubling dilution (dd) shift in the provocative concentration of methacholine required to reduce forced expiratory volume (FEV1) by 20% (PC20). However when adding nasal fluticasone to the inhaled steroid, there was a 1.79 dd shift. This difference (0.58 dd, 95% CI 0.78, 1.95) was not statistically significant. However the combined treatment did result in significant improvement in rhinitis quality of life, nasal inflammation and inspiratory flow.

The investigators will repeat this previous concept, but compare intranasal fluticasone with azelastine (an antihistamine) nasal spray versus placebo nasal spray, in atopic asthmatic patients on inhaled steroid. This will be to assess effects on methacholine PC20, the primary outcome, and to assess the effects on the following secondary outcomes: Exhaled nitric oxide (FeNO), FEV1, morning peak expiratory flow (PEF), impulse oscillometry, peak nasal inspiratory flow (PNIF), nasal nitric oxide (NO), blood eosinophils, eosinophilic cationic protein (ECP), nasal symptoms, asthma control and quality of life; and rhinitis quality of life.

Twenty adults 18 and up, with allergic asthma will be enrolled. They will have a run-in on 2 weeks of 200 micrograms beclometasone inhaler and then be randomised to add either intranasal fluticasone and azelastine, or placebo nasal spray to their treatment (double blind). Treatment period one will be 3-5 weeks followed by a washout of 2-4 weeks, and crossover to treatment period two for 3-5 weeks. Due to the crossover nature of this study participants will receive both treatments in random order. There will be an Interim analysis after 20 participants complete the study per protocol and the exact required sample size will be recalculated (Pocock/adaptive design).
